TRAVELING DERRICK.

SPECIFICATION forming part of Letters Patent No. 414,218, dated November 5, 1889.

apolis, in the county of Minnesota, have invented certain new .and useful Improvements in Traveling Derricks, of which the following is a specification.

My invention relates to that class of derricks operated,preferably,by constantly-running power, and adapted to the lifting and transferring from pl cry or other heavy articles, while themselves capable of being moved to and and it consists, generally, in the construction and combination hereinafter described, and particularly pointed out in the supports;

I prefer to make this traveling connection in the following manner:

Any suitable means may be employed for adjusting the tension of the driving belt or rope 15 to preventslipping upon its drums or wheels.

In Figs. 8, 9, and 10 are shown a modified construction for use on platforms, docks, decks of vessels, and other places where there is no travel are supported and travel the wheels 92, which carry the upright frame 93 and its attachments. The rail 91 is provided with a suitlifted or thrown from the rail. transmitted by means of the drums 97, 9S, and 99 to the shaft 100, the

or wheels operation of the derrick and its attachments being the same as above described in reference to the form.

Fig. 7 represents another modified construction of hand power derrick having similar supports, connections, and means for running the derrick to and fro, and also for swinging the crane, except that the power is applied by hand and not through a constantlyrotating shaft driven by outside power. The main shaft 101, supported in suitable bearings centrally and vertically in the derrick-frame, is provided with the fixed bevel-gears 102 and 103, meshing into other bevel-gears 104 and 105, by means of which the pinions engaging the racks on the supporting-rails are turned to carry the derrick to and fro, as above described. The shaft is also provided with a slidable bevel-gear 106, the position of which is controlled by a suitable pivoted lever 107, having suitable connection with it, as by a collar lying loosely in a groove in the hub of the gear linked to the lever. A suitable drive wheel 108, carrying an endless band rope or chain 109, is journaled to the derrick-frame, its shaft carrying the bevelgear 110. By means of the lever 107 the bevel 106 may be thrown into engagement with the bevel-gear 110, the lever engaging a suitable toothed rack 111 on the derrick and holding the gears in engagement with each other. By means of the band-rope the Wheel 108 may be rotated in either direction, and thus through the gearing and shafting described cause the derrick to travel in either direction. The derrick is rotated by means of the crank 112, operating the worm-gearin g 1 13, which in turn through its shaft 111 causes the pinion 115 to travel around in the circular rack 116 of the base. The lifting-chain is operated by the windlass 117 in the ordinary manner.

If desired, a suitable jacket may be socured around the frame of the derrick, so as to inclose and protectall of the machinery of the derrick.

I claim as my invention 1. A derrick having a suitable base supported and adapted to be moved longitudinally of a supporting rail or track, a cranecarrying frame pivotally supported upon said base and having traveling support for its top adapted to be moved in a parallel direction to that of the base, and means for propelling said derrick to and fro on its support and for rotating it upon its base, combined and adapted to be operated substantially as described.

2. In a derrick, the combination, with carrying and guiding fixed rails along which said derrick is adapted to travel, of racks rigidly secured to said rails, a continuously-running vertical shaft arranged in said derrick, loose gears arranged upon said shaft, connected,

, respectively, by suitable mechanism with said racks, with a Windlass upon said derrick, and with the base of the derrick, and clutches slidably adjustable upon said shaft, and adapted, respectively, to engage said gears, and thereby to propel said derrick to and fro, or to rotate the same upon its base, or to operate said Windlass, substantially as described.

3. In a device of the class described, the combination, with a circular base having a geared periphery supported upon a Wheel adapted to run upon a fixed rail provided with a rack, of a crane-carrying frame pivotally supported upon said base, and also pivotally connected at its top to a horizontal frame secured to and adapted to be moved along a fixed support provided with a rack and parallel with said rail, a continuouslyrotating main vertical shaft supported in said frame and provided-with loose gears meshing into similar gears fixed on secondary shafts, said secondary shaft-s being connected, respectively, by means of other shafts and gears with pinions engaging said racks and the peripheral gearing of the base and with the Windlass of the derrick, and clutches arranged on said main shaft and adapted to engage said loose gears, whereby power may be transmitted through said secondary shafts and their connections, so as to propel said derrick forward or back on its support, or to rotate the same in either direction upon its base, or to rotate the Windlass in either direction, substantially as and for the purpose specified.

1. The combination, with a derrick, of a fixed supporting-rail adapted to carry the derrick, and a guide-rail with which the top of the derrick has traveling connection, mechanism, substantially as described, engaging said rails and adapted to move said derrick along the same, a continuously-running vertical shaft carrying loose gears connected with said mechanism, and clutches arranged upon said shaft and adapted to engage said gears, and thus to transmit motion to said mechanism and to propel the derrick, substantially as described.

5. The combination, with the derrick, of the supporting-rail 3, having the rack 26, the rail 19, having the rack 27 and arranged parallel with the rail 3 and furnishing support for the top of the derrick by means of traveling connections, the pinions 28 and 29, respectively arranged to mesh into said racks, the main shaft 9, arranged to rotate in bearings in the derrick-frame, and gear and shaft connections between said shaft and said pinions, by means of which said pinions are rotated by said shaft and the derrick propelled along said rails, substantially as described.

In testimony whereof I hereunto set my hand this 29th day of April, 1889.
